Good to hear! I'm using XFCE4.
I created the file using emacs without naming any file extension. I tried the same in nano, the same result.
Whenever I name the nano- or emacs file 'network' or 'networks' the issue arise.
When naming the file network.txt no problem at all.
I've created 20 files in nano and emacs and none of them get's recognized as an Amiga SoundTracker file, but rather as .txt & .sh files.
